“The glass that’s used in these big sunroofs, it’s not the glass that is used in your windshield where if a rock hits it, it cracks but it doesn’t shatter,” said Consumer’s Union David Friedman. “This is a problem that exists across many automakers, across many models. They’re really expensive to fix and car companies, in many cases, are refusing to step up and cover the cost for their consumers.”

Several cars have been recalled including one Hyundai to fix shattering issues.
